No need for rheumatoid factor testing, GPs told

Comment

Rheumatologists are requesting anti CCP( cyclic citrulinated peptide) more these days . Anti CCP test has a sensitivity of around 80% and more importantly a specificity of around 90%. Rheumatoid factor is sensitive but certainly not specific enough . Depending on your local lab ( ours in Liverpool do anti CCP for GPs) . the test TOGETHER with history and examination should give you the diagnosis reliably.
